SPECIFICATION forming part of Letters Patent No. 368,712, dated August23, 188?.

Application filed May .22, 1886. Serial No. 203,017. (No model.)

T0 aZZ whom it may concern.-

Be it known that I, GUSTAVUS A. Gnssnnn, of Fremont, in the county ofSandusky and State of Ohio, have invented a certain ImprovedBottle-Stopping Mechanism, of which the following is a specification,reference being had to the accompanying drawings.

The object of my invention is to provide an improved stopper mechanismof that class adapted to be applied to bottles, as ordinarily made, witha lip, annular flange, or projection around the top of the neck at themouth of the bottle, the lip in all cases serving as a stop or hearingto resist or encounter the force applied to press the stopper down toplace for sealing the bottle. In this class of bottle-stoppers the capor stopper is forced down to place in or over the mouth of the bottleperpendicularly without rotating it, by which injury to thestopper-packing is avoided.

In the accompanying drawings, illustrating my invention Figure l is aside view of an ordinary bottle-neck with part of my improvementsapplied. Fig. 2 is a side view taken at right angles to that of Fig. 1,and showing an open instead of a closed cap, as in Fig. 1. Fig. 3 showsa side view, partly in section. Fig. 4 shows a vertical diametricalsection of the bottle-neck with my improvements applied,

the cap being open and provided with my improved valve mechanism. Fig. 5shows the telescopic nozzle detached and partly in section, disclosingthe valve-operating structure. Fig. 6 shows an addition, not belongingto my invention, by which what is called a siphonbottle is convenientlyproduced when my inmade of one piece of plate metal bent and united atits end, or of two semicircular pieces united. In this instance I formmy loose ring larger at the top than at the bottom, with a ledge, E,between the two parts, and extend its enlarged upper part up around thelip, leaving a small annular space between it and the lip. I alsoprovide two or more inclined threads, F, upon the inside of the enlargedupper part of the ring, with spaces or plain surfaces G between them.These threads are preferably formed by cutting inclined slots in thering and bending in the upper edge of the cut, as illustrated.

My cap or stopper Z is formed with coincident inclines or threads H,projecting outward and adapted to engage with the inclines or threads ofthe ring. This cap is provided with any suitable packing, and is placedwithin the enlarged upper part of the ring, which latter is then turned,when the threads or inclines slide upon each other in the usual way todraw down the cap perpendicularly without turning it to seal the bottle.

I may employ either a closed cap, as repre sented in Fig. 1, forbeer-bottles, &c., or an open cap, as shown in Fig. 2, for stoppingbottles containing aerated liquids, or liquids charged with gas. When mystopper is used for the latter purpose, I form an opening through itstop and secure a tube, K, around it. Beneath the cap I provide avalve,L, the stem M of which, being preferably a screw, as shown, passesthrough the guide N and through the perforated bottom O of a slidingcylinder I? within the tube K, which also acts as aguide. The parts areso adjusted that the valve-stem and cylinder 1? have a little verticalplay, so as to open and close the valve.

WVhen the bottle is empty,the valve will normally be open--that is, itwill drop down by force of gravity so as to open. When the bottle isfilled with aerated liquid under pressure, it will press up the valveand close it, the guide N having openings 00 on either side of it ofgreater area than the perforations in the bottom of the sliding cylinderP, which dispenses with the use of a spring to operate the valve.

I provide for opening the valve when it is filled and for thusunstopping the bottle by means of a telescopic nozzle, Q, which iscomposed of an external pipe, R, having a flange or any suitableprojection or thumb-piece, S,

around its base, and an internal push-tube,T, adapted to enter withintube K and bear against the upper end of the cylinder P. By

ICO

pressing down upon the flange or thump-piece S the valve will be presseddown within the bottle-neck enough to open it,when the contents of thebottle will spout out of the nozzle 5 under pressure in the usual way.The instant the pressure is relieved from the thumb-piece S the valvewill automatically close,unless the bottle is emptied, and seal thebottle, the same asin devices Where a spring is employed to IO close thevalve. The nozzle can be readily detached, as, in fact, can all of thestopper mechanism and all of its parts,which renders it very convenientfor transportation,repairs, or trans fer in case of. breakage of abottle. I 5 If desired, a tube, as indicated at U, Fig. 6, can beattached to the cap around the valve, and extend to near the bottom ofthe bottle, and the nozzle can be given a half-turn, as indicated inFig. 6. This will produce What is known as a siphon-bottle, which can beemptied without turning it down. In this manner, by using myimprovements, an ordinary bottle for ale,beer,or other liquid. underpressure can readily be converted into a siphon- 2 5 bottle. I

My improved stopper has all of the wellknown advantages of this class ofstoppers in addition to those peculiar to its specially-improvedconstruction, rendering it simple, economical, durable, and effective.The valve structure,by which I secure an automatic closing of the valvewhenever the bottle is not entirely empty, without employing a spring,is of great practical importance, as there are many objections to theuse of a spring for work- 3 5 ing the valve. All the parts can bereadily stamped out of sheet metal, and are light and inexpensive.

Any suitable packing can be used with my improved stopping mechanism,both in the 40 cap and upon the valve; but my improved seal, consistingof combined rubber and paraffine paper, for which I have applied forLetters Patent of the United States, is preferable.

\Vhat I claim is- 1. In combination with an ordinary bottleneck having alip, B, the ring 0 and cap Z, adapted to fitwithin the upper enlargedpart of the ring and engage therewith by screwthreads, substantially asset forth. 5o

2. In a valve mechanism for a bottle stopper, the combination, with avalve having a stem attached to a hollow sliding cylinder with aperforated bottom, of the cap provided with aguide, N, and openingsabout it of greater area than the perforations of the sliding cylinder,substantially as set forth.

3. In combination with the cap Z, the guide N, tube K, valve L, stemM,sliding cylinder P, and telescopic nozzle adapted to be pushed down toopen the valve, substantially as set forth.

In testimony whereof I have hereunto subscribed my name.
